Use the Java hierarchy you posted in my code below and add a user-defined exception that can be thrown by one of the methods as part of the validation or error checking. The main method should then make a instance of the class and call the method in such a way that the exception is thrown (e.g. invalid input or state of the system). Submit your program as an attached .java file and post a screenshot to show that you have been able to successfully run that program. File is Widget.Java
